Specification of Letters Patent.

Patented Aug. 9, 1921.

Application filed September 15, 1920. Serial No. 410,502.

T all whom it may concern Be it known that I, Josnrn ZAKARKA, a

' citizen of Lithuania, residing at Brooklyn,

county of Kings, and State of New York, have invented certain new and useful Improvements in Bag-Holders, of which the following is a specification.

This invention relates to a bag holding device to be used in connection with the sugar packin machine forming the object of my U. S. atent No. 1,350,130 of August 17, 1920, and it is the principal object of my invention to provide a device of this character, which allows the rapid filling of the bags with the sugar delivered from the chute of the measuring device.

A further object of the invention is to allow a convenient closing and handling of the bags" after the filling, by an apparatus characterized by its simplicity of construction.

These and other like objects and advantages of my invention will become apparent as the description proceeds, reference being had to the accompanying drawings forming a material part of this invention, in which Figure 1 is an axial vertical sectional view of a bag filling apparatus constructed according to my invention.

Fig. 2 shows in detail top plan view and side elevation, one of the bag clamping members.

Fig. 3 is a horizontal section taken on line 33 of Fig. 1.

Fig. 4 is a side view of the bag holding device.

In the drawings, 10 indicates a portion of one of the floors of a building, such as a sugar refinery, and 11 is one of the vertical walls thereof. Supported on the floor 10 1s a hopper 12 having its discharge mouth extended downwardly through the floor in form of an extension 13. At the lower end of this extension 13 is a door provided with a handle 14 whereby it may be opened or closed.

Located below, and in axial alinement with the discharge mouth of the hopper is a cylindrical measuring chute 15 of slightly larger diameter than the said mouth, this chute extending downwardly through, and being supported by, a platform 16, located at a distance below the floor 10 and supported in any suitable manner.

Supported by the platform 16 is a welghing device of the steelyard type, commonly referred to as a scale. The pan of this scale, which will be presently further referred to, extends under the chute 15 and normally closes the lower end thereof. The frame of this scale comprises a hollow post 17 eX- tending through and suitably supported by the platform 16 and having a lateral lug on its upper end to which is fulcrumed as usual 21 scale lever of the customary type provided with the customary movable balance weights. Suspended from the inner end of the scale lever is a rod which extends freely through the post 17 and has a rigid foot 18 on its lower end to which the pan is secured. This pan comprises a pair of semi-circular halves l9 and 20 formed on one side with laterally projecting lugs widening into a pair of gear segments, one of which, 21, is shown in Fig. 1. These gear segments are, operated to separate the halves of the pan by means of a rack bar 22 vertically slidab-le in guides 23 in the platform 16 and engaging a spur gear rotatable on a bracket and having fixed co-axially thereto a bevel gear 24 meshing with a pair of smaller bevel gears 25 and 26, the former of which is mounted on the foot 18 and the latter on an extension 27 of the bracket. The gear 25 has fixed co-axially thereto a planetary gear 28 which meshes with one of the gear segments, while the gear 26 has fixed thereto a spur gear 29 meshing with the gear segment 21. The bar 22 has a fixed head 30 adapted to be depressed against the action of a spring 31 by the foot of the operator, the spring 31 automatically returning the bar to raised position with the pan halves united.

Extending downwardly from the chute 15 in axial alinement therewith is a delivery funnel 32, the upper end of which is spaced below the lower end of the chute 15 just a sufiicient distance to accommodate the pan of the scale, the upper portion of this funnel, tapering down to a restricted neck 33 provided with a swinging door operable by a handle 34. This funnel may be supported by a bracket 35 fixed to the wall 11.

The bags 36 to be filled are secured to oval clamping devices 37 illustrated in detail in Fig. 2 which are fixed to the ends of arms 38 radiating from a hub 39 on a standard 40. This hub 39 is provided on each of its sides with two stationary stops 41 leaving a space 42 between them within which the inner ends of the arms 38 are pivotally secured as at 43 to the hub. The

and 46 over the material 47 at the upper end of a bag by the engagement of the inner ridges 48 and 49 on'said clamping members in a groove 53 on the outer edge of an oval hoop 54 secured with one end as at 55 to the leaves 44. Itwill be clear that the material of the bag is clamped between the ridges 48 and 49 and the grooves 53 of the hoop 54 and firmlyheld therebetween.

After the bag has been filled, it isclosed in the ordinary manner after the clamps and the hoop have been removed therefrom,

and is then conveyed away by means of the endless conveyer 56 of any ordinary well known type and driven by any suitable means. In operation, the empty bags are Secured to the hoops by the clamping members and swung by the arms under the funnel and whenfilled they are disengaged from the clamping members and the hoops, closed, and carried away by means of the conveyer.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. In an apparatus of the character described, a bag holding device comprising a post, a hub rotatably secured to said post, a plurality "of arms pivotally secured to said hub superposed platesisecured to the outer ends of each of said arms, movable clamp elements pivotally secured at their outer endsbetween said plates,itoothed segy ments in mesh with each otherat the outer ends of said clam elements, and handles at the opposite ends of said clamping elements for allowinga clamping of the same over the materialofa'bag to hold thesame open while it is in the process of filling.

2. In an apparatusof the character described, a bag holding device comprising a post, a hub rotatably secured on the upper end of said post spaced stop fingers atthe four side edges of said hub, radial arms pivoted to said hub between alpair of said stop fingers, superposed plates "secured to the outer ends of said arms, 'clamping'members pivotally secured to the outerends of said arms, clamping members pivotally secured between the plates, ridges on the inner side edges of said members toothed segments at the inner ends of saidmembers in mesh with each other, an oval hoop secured to the upper oneof said plates and having a groove in its side edge for the reception of the ridges of said clamping members when the same are clamped'over the material of a bag, and handles on the opposite ends of said clamping members for operating the same. c

In testimony whereof I have afiixed my JOSEPH ZAKARKA.
